Pro: Curious how you keep your foot pedal controler from shifting/moving around while performing? Is it is secured to the floor (carpet?) in some fashion?

In my setup, I mount my foot pedals (actually 3 of them) to a piece of 1/8" plywood, using industrial strength velcro snap mounts made by Littlite:

and place the piece of plywood on the floor under the KB. The plywood is kept from moving about by the back tube bar (along the floor) of the Monolith Stand.
